This application is a division oi my prior application SerialNo. 188,446, led October e, 1950, which has matured into Patent No. 2,595,895, granted May o, 1952.

This invention relates to new and improved ieatherless insoles of maximum flexibility and strength for longer wear and greater wearing comfort even when the shoe incorporating the new insole is new. "The principal object of the invention resides in-the provision of a flexible'insole having'nc feather even in the blank 'and being less in size at the forepart than the sole of the shoe or ofthe uott'ornrof" the last to be used and being provided with heel and forepart r'n'arks defining the shank, the `forepart being reduced and there being a tape secured to the insole from the heel mark, lalong the shank inset from an edge thereof, Aaround the forepart of the extreme edge, Aand back along the shank at the opposite edge and also hereinset, to the heel mark once more; in combination with two separate secured on tapes at the shank only contiguous to the shank porvtion ofthe tape mentioned, the tapes being lip set and cemented to form a strong rib, with no channeling at all in the-insole.

Other objects include a reduced iorepa-rt` either splitroff orV made in two parts, a heel and shank snperposed on a thin member of insole form; a

cover aiding the erection of the forepart rib, Aand vReference is to be'had to accompanying drawings in which:

Fig. 19 is a section @nime isi-ls of Fig. 1e.

Fig, l shows an insole blank I'U rounded-or shaped on the solid line to a size smaller than the insole of a prior art shoe of exactly the same size as snownin dotted lines at |2 The dotted lines 'also ofcourse show the outline of the last bottom for both'A the new shoe and the prior art shoe.

"The new insole: is next scored at the h-eel as at line lll which indicates in general the heel breast line of the sole; also a mark l G is made across the f orepa'rt. The marks 4` and |`6`include the shank of theblank -v vhich is preferably beveled at the edges i8 and 2 Il', between the" two lines for neater tpf the dover and better insole appearance, as wli'te explained.

The mark i6 acts also as aV guide by which the length of forepart reduction is gauge'd, the next step being to 're'dicef the entire forepart as at 22. The reduction of the forepart lends flexibility to the insole without loss of strength or wear, but itwold not bepossible to so reduceV the forepart 'if the" oldv prior art channeling-for obtaining the `secured ribfw'ere to: be carried o't. This invention obl'nple'telyy avoids all channeling and vat thesa'me time provides a stronger and In'ore'e'xible insole. ,I

Next, la -log'tape 2livv is secured flatly to `th`e blank by ei'therbernenting or stitching on'Y line' 26 at thefe'dgeof theforepa'rt' and onA intoj the shank bar insetfndm the enges therein. This tapestarts atma'rkjifd Yandri'ms' around the toe'an'd back to themaf" see-Fig; 4,A the' markindieating 1;'0 the operatorw ere' to start-and stop.

TheV tape' itsel'f is folded over lengthwise" and cemented to start; with, see Fig. 5, and the line'2'6 rims throgh the folclf'gil' ornear thefld, so' that the threads cannotpull dueto frayingr of the fabrie'pf which the tape is pr'eferabn made irl the event linef26 represents stitching.

'The next' step includes the'seourng oftwo separate short flat lengths of tape as at 30 between the marks I4 and IB and to one side of the tape 24, in the shank area. The fold 32 lies next to fold 28 and in substantially contiguous relation thereto; see Fig. 7. The tapes are cemented and lip set (moved up and toward each other) to flatly conjoin them into a relatively thick, multiple secured rib such as is required at the shank, see Fig. 8, wherein the major part of the tape 24 about the forepart has not been raised up and is still flat on the blank, but theshank rib has now been made. In this operation the tapes are raised up and rmly pressed together resulting in the conformation shown in Fig. l2.

The cover 34 is cemented to the side of the insole opposite the tapes. The edges of the cover are folded over and cemented to the tape 24, Figs. 9 and l0, by a device which raises the tape up to conjoin with the cover which helps hold the now made forepart rib upright, see Figs. 13 and 16.

A layer of gem duck 36 is then applied and cemented to the tape 24 throughout and in the forepart and shank, thus strengthening the rib further.

Figs. 18 and 19 show a modified blank made of two parts 38 and 40 superposed, avoiding the reduction step at 22 but otherwise presenting the same invention as that described.

This invention can be made without any reduction in the forepart at all; and the cover is not a necessity in all of the new insoles, being capable of omission if desired.

In any event the new insole is featherless, and the feather is not removed, it never existed at all in this invention. The invention has the advantages of extreme ilexibility of the sole without any loss of strength in any part, the forepart is thin and devoid of channels and will always stay flat and not gutter or curl at the edges; the absense of feather lends wearing comfort from the very start even when the shoe is new; and the shoe is better made throughout due to close inseaming at the last bottom, better and smoother pulling over on the last bottom edges, which are exposed, see Fig. 17; and the less bottom filler is needed, adding to flexibility.

This construction is an improvement over the channeled in shank method because a cheaper and lighter leather or like material which is not suited for channeling can be used. This method of making upstanding ribs in the Shanks is stronger than channels which are dependent on the leather fibers for strength.

Some of the eonstructional and functional advantages are apparent from an inspection of Fig.

17 wherein the last is shown at 42, the outer sole at 44, and the welt at 46. The insole edge terminates at 48, but the edge of the last bottom extends well beyond the insole edge as at 50. Hence the upper 52 clearly can and does conform exactly to the last edge and outline; the missing feather cannot curl up; the welt, outersole, and other parts are sewed exactly as always before without the need of new machines; the pulling over operation is simpler to accomplish and is smoother and in exact conformance to the last edge; and the other objects and advantages of the invention are seen to be carried out in a practical manner easy for any Shoemaker to understand and follow, once the inventive concept is presented as above.

Furthermore, this invention has shoe making advantages including the fact that it is much better for and makes easier the automatic toelasting operation because since there is no feather there is no change of buckling the insole in the over wipe. More uniform margins may be maintained because the human skill of channeling is done away with, the edge of the new insole itself guiding the securing of the tapes. There is no guttering so that again the insole and also the outsole will always stay at; there is a better cushion effect and more flexibility due to the thin forepart and there is longer wear of the outsole due to more even distribution of weight and pressure over a greater wearing area.
